Thicke unveiled "Get Her Back" with the intention of doing just that at the Billboard Music Awards. Over minimal bluesy guitar strumming, Thicke reflects in his signature rasp, "I gotta treat her right / I gotta cherish her for life / I gotta go get her, go get her, go get her, go her tonight / I never should have raised my voice / Or made you feel so small."

Watch the performance above showcasing the blue-eyed soul singer looking humbler than ever, opting out of his signature aviator sunglasses and gelled-out hair for a casual t-shirt-and-leather-jacket combo and buzz cut.

Also during the BBMAs, Thicke gave a shoutout to Patton in his acceptance speech for Best R&B Song. "Most importantly, I'd like to thank my wife for her love and support and for putting up with me all these years," he said.

Despite initially announcing they had "mutually decided to separate," it's become clear Thicke's on a mission to win back his love of 20 years. The retro-tinged singer recently dedicated a cover of Al Green's "Let's Stay Together" to his actress wife.

Your move, Paula. No, seriously, make a move. We can't help but feel bad watching Robin spill his heart out again and again.
